Thanks, moved this up on the list a little (it's a known thing).
Another thing you can try: the node pre-generates a small set of roughly 2 second long noise buffers when it "turns on", so until this is fixed, one thing you can try is deleting it, then undo (or just create another white noise node), which should generate another pass, with a chance for a less obvious loop.
In melody controlled mode, the node will also randomly pick different noise buffers for each note played, so that can also help if you can stitch the desired sound together with a sequence of notes.
